Specification of Letters Patent.

Patented Nov. 7, 1911.

Application filed April 15, 1910. Serial No. 555,572.

To all whom it may concern:

Be it known that I, JOSEPH O. ANGER- MEIER, a citizen of the United States, residing at Inglefield, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in gas generators and particularly to gas generators used in the manufacture of acetylene gas; and an object of this invention is to provide an acetylene gas generator which will be simple in construction, relatively cheap in first cost of installation, durable in use and highly efficient in operation and of which the cost of upkeep will be comparatively small.

Another object of this invention is to provide an acetylene gas generator with simple and reliable means for controlling automatically the flow of carbid to the generating chamber.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure 1 is an elevation of my new generator, parts being broken away to illustrate more clearly the interior construction; Fig. 2 is a plan; Fig. 3 is a detail, partly in section, of the funnel and the swinging gate or shutter which controls the outlet of the same; and Fig. 4 is a fragmentary view showing the shutter-controlling devices in different positions.

The generator a consists of a body I) from which rises a tower c. To the base (Z of the latter is riveted a top or dome e in which is mounted a carbid-holder f having a funnelshaped base 9 from which projects downwardly a cylindrical spout h that forms an outlet through which flows the carbid. The body 6 forms a water-tank and its walls inclose a generating chamber 1' in which is formed the gas by the chemical reaction between the water and the carbid and from which flows the gas so formed through the pipe j into the gas-tank 7c. The latter is provided with the usual gas-bell m which is provided with a rigid post or upright arm a that carries a pin 0 which travels in a slot p formed in a lever g fulcrumed on a bracket T which is fastened to the outside of the dome e. One end of the lever g is pivotally connected with the upper end of a link-- bar 8 the lower end of which is fastened to an L-shaped link-rod t the vertical leg of which extends down through a pipe a mounted in the water-tank Z) and having its lower end lying below the water-level therein. The base of the L-shaped link-rod t is connected by the link-rod o to one side of a V-shaped gate or shutter w the other side of which is formed with an opening w near the line of junction of the two sides (F ig. 3). Just above the spout it there passes through the funnel-shaped base 9 a shaft m on the projecting ends of which are mounted free to rock or swing, pendulum-like, the arms 3 which extend upwardly from the V-shaped gate or shutter w and serve to pivotally connect the same with the shaft a".

The gas-bell m is provided with the guide brackets m which are mounted free to slide along the vertical guide-post m.

A pulley-holding bracket 2 is mounted on top of the dome e and carries a pulley 3 over which passes a chain 4 to the free'end of which is attached the weights 6. The chain 4 passes down through a pipe 5 mounted in the water-tank Z) and having its lower end curved upwardly or hook-shaped so as to provide a guide for the chain 4 in its change of direction. To the end of the chain 4 which lies in the generating chamber i there is attached the lower end of a rod 7 which passes through a guidetube 2 depending from the funnel-shaped base and the upper end of which is attached to the follow-up plate or follower 8.

As the carbid flows through the aperture to in the gate or shutter w, the follower 8 rests upon the top of the carbid and sinks, as the level of the carbid falls. As the follower 8 descends, the weights 6 also fall, thereby taking up the slack of the chain 4 and keeping the latter taut. The position of the weights 6 indicates the amount of carbid remaining in the holder f.

As the gas in the gas-tank 70 increases in volume, it presses upwardly the gas-bell m and thereby swings the lever q on its pivot, as is indicated by the dotted lines in Fig. 1. As the slotted end of the lever g swings up wardly, its other end forces the link-bar .s' downwardly and thereby pushes down the L-shaped link-rod t. The downward movement of the latter is transmitted through the link-rod o to the shutter 10, whereby the latter is swung on the shaft 00 to the dotted line position shown in Fig. '1. In the latter position the shutter cuts on the flow of carbid to the generating chamber 2' through the spout h. It will be observed that a comparatively small upward movement of the gas-bell 'm is suflicient to throwthe shutter w from its full-line position in Fig. 1 to its closing or cut-off position shown in the same figure by dotted lines. Further upward movement of the gas-bell does not move the shutter w but results in the link-bar 8 being swung upon the top'of the link-rod t as a pivot point, as is indicated in Fig. 4.

. Should the carbid fail to flow freely, the

gas-bell will descend, thereby bringing the shutter w so that its aperture in lies under the spout h; and should a large quantity of the carbid later become loosened and suddenly fall, the shutter w will intercept the device which is connected at its upper end to said shutter; a second link device which is connected at its upper end to said lever; and a third link device which is jointed to the lower ends of said link devices, said sec- 0nd link device being adapted to swing from side to side upon the upper end of the lastnamed link device as a pivot point and thereby to permit the movement of said gas bell and lever, after said shut-ter has reached the limit of its'swinging movement.

2. The combination of a generator; a carbid holder mounted therein and formed with an outlet; a gas-tankconnected with said generator; a gas-bell slidably mounted in said gas-tank; a lever having a slotted end which is slidably connected with said gas-bell and is adapted to be swung thereby; a shutter which is mounted free to swing and is adapted to control the flow of carbid from said outlet; a link device the upper end of which is connected to said shutter; a second link device which is connected to said lever; and an L-shaped link device which is interposed between and connects the lower ends of said link-devices; said second link device being adapted to swing from said side upon the upper end of said L-shaped link device as a pivot-pin and thereby to permit the movement of said gas-bell without corresponding movement of said shutter.

3. The combination of a generator; a carbid holder mounted therein and formed with an outlet; a gas-tank connected with said generator; a gas-bell mounted free to slide in said gas-tank; a shutter mounted free to swing in close proximity to said outlet and adapted to control the flow of carbid therethrough; a pair of link devices mounted in said generator, the lower ends of said link devices being jointed together and the up per end of one of said link devices being connected to said shutter to swing the same; a lever formed with a slotted end which is slidably connected with said gas bell and controlled by the latter; and a link device which connects said lever and the upper end of the other'of said link devices and which "swings on the last-named upper end, during the movement of saidgas-bell and lever after said shutter has reached the end of its swinging movement.

In testimony whereof I have hereunto set my hand in the presence of the two undersigned witnesses at Evansville, Indiana, this thirtieth day of March A. D. 1910.
